This resource is about graphing equations where the algebraic representation is given. This is a continuation of, Writing the Symbolic Representation of a Function. If you have not viewed that resource, you should start there.

This resource is actually easier because you will be given an equation and a graphing calculator. The important part will be to make absolutely sure you have the correct graph. This resource will emphasize checking, double-checking, and triple-checking to make sure you are correct 100% of the time.

First, you need to review the slope-intercept form of linear equations where m is the slope and b is the y-intercept.

y = mx + b

Remember that there are three types of slopes in linear graphs. Look at the graphs below.

Positive Slope

Graph of the line y equals x minus four

Negative Slope

Line Graph of y equals negative one half x minus 6

Zero Slope

Graph of the line y equals negative one

A link provided below will take you to an interactive website where you can match graphs with a given equation.

Read the directions and then follow the link below.

Instructions

  1. Move the mouse to graph the line given in slope-intercept form.
  2. Click "Submit" at the bottom.
  3. "Excellent!" will appear, and a line with a new line to graph.
  4. Keep practicing until you get five straight correct answers.
